Nos. 1 , 2, and 4 are boiled refuse bones of glue makers. 
No. 3 is genuine raw bone dust, not very clean, but on tbe 
whole, of fair average quality. 
No, 1, boiled bones, contains one-fourth of its weight of water, 
and contains more sulphate of lime, salt, and sand than genuine 
boiled bone dust. 
Nos. 2 and 4 are too wet, but they are otherwise genuine boiled 
bones ; and No. 4 contains rather more sand than it ought. 
Assuming No. 3 to cost 8?. a ton, the comparative money 
value of these four samples will be : — No. 1, 5Z. a ton ; No. 2, 
6Z. 15s. a ton ; No. 3, 8Z. a ton ; No. 4, 6Z. 6s. a ton.* 
A sample of guano was sent for analysis by Mr. Samuel 
Fitton, Cheerbrock Farm, Nantwich, who stated that he 
bought the guano from Messrs. W. Shaw and Co., Liverpool, at 
14/. lOs. per ton, delivered at a station near Nantwich (less 5 per 
cent, for cash), guaranteed pure. 
The analysis showed that the guano was much adulterated 
with sand, gypsum, and earthy matter, and in consequence 
* The samples 1, 2, 3 -were sent on February 2 by Mr. Leather, Delamere 
Lodge, North wioh, and on the 15th the following letter was received from him 
with sample 4 : — 
" Dear Sir, — The sample of boiled bones recently analysed by you for me was 
given to me as genuine by Mr. Robt. Ashworth, of Frodsham. On showing him 
your analysis, he stated that the sample of bones given me was taken from 
' sweepings,' and was not a fair sample. This he appeared to think would explain 
the large proportion of water as well as sand. He has given me, therefore, a fresh 
sample, which I forward to you to-day for analysis. 
" Yours faithfully, 
" Simeon Leather." 
In a subsequent letter Mr. Leather gives the following as the prices of the 
several samples, and the names of the dealers who supplied them : —
